Abstract
In an Advanced Intelligent Network, a central mediation point stores call processing records for controlling call routing and other call processing functions. To provide short code access to information service providers, each information service provider will operate an independent database which stores additional call processing records. When an established subscriber dials the short code, e.g. an N11 code, the mediation point identifies the information provider that the subscriber has previously selected from the subscriber's call processing record stored in the mediation point. The mediation point communicates with that service provider's database to obtain call processing information. The mediation point validates the call processing information for compatibility with network operations. The mediation point forwards validated call processing information to a node of the network to process the call in accord with the information from the provider's database. If the caller has not pre-selected one of the provider's or the caller dials one alternate short code, the network will prompt the caller for a selection, and then obtain the necessary call processing information from the d…
